Maternal Vitamin Levels and Infant Birth Weight in a Pregnancy Trial

57 mother-infant pairs from the Exercise Training in Pregnancy Trial (ETIP) with plasma vitamin A, D, and E measurements in the second and third trimesters. The dataset includes infant birth weight classifications and was published by Astrid Kamilla Stunes under a CC-BY-4.0 license. The data was last updated on 2026-04-15.

Use Cases

• Analyze trends in maternal fat-soluble vitamin concentrations across pregnancy trimesters based on retinol, 25(OH)D, and α-tocopherol measurements.
• Model associations between maternal vitamin levels and infant birth weight outcomes based on normal weight and macrosomia classifications.
• Investigate the prevalence of vitamin insufficiency and deficiency in a population with overweight or obesity based on the reported percentages.

Strengths

• Includes longitudinal measurements of three key vitamins (A, D, E) across two pregnancy trimesters.
• Provides specific mean concentrations and standard deviations for each vitamin at each time point.
• Reports clear prevalence statistics for vitamin insufficiency (19.3% for A) and macrosomia (43.9%).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (16.8 KB), indicating limited scope and sample size.
